ok. working up a simple cabled scarf....42 stitches across with an 8 row simple pattern repeat....shouldn't need to use lifelines.....WRONG! i had to throw the WIP down and take off for a code and when i get back (the patient didn't make it) somehow i drop a stitch and unconsciously yarn over or something to replace the stitch. i complete 2 more 8 row sets when i notice a ladder falling thru the purls b/n the cable and a rib. *sigh* i learned the hard way that you can't fish for and pull a dropped stitch through cables very well. only had to rip out 20 rows. must always use a lifeline.
